UK mobile service revenue growth was -0.1% in Q4, a 0.6ppt improvement from the previous quarter. This was helped by some modest price firming, continued strong data growth, and some inflation in handset prices

EE was the strongest growing operator after being the weakest just 12 months ago, with its efforts to improve customer service, network performance and perceptions of network performance starting to pay off. H3G had a strong H2, with strong customer additions while not sacrificing ARPU, although it is still clearly taking steps to manage capacity demand. O2 had another solid performance with a modest improvement in service revenue growth, and Vodafone suffered from weak ARPU primarily due to pricing pressure in the business market

The outlook for market service revenue growth is fairly positive, with ARPU-enhancing pricing moves in evidence, supported by continuing strong data volume growth, and existing customer price increases due to take effect from Q2 2017

Fashion underpins the growth of ecommerce; online took a 14% share of all fashion retail in the UK last year and is set to rise further, challenging the economics of physical retail 

Mobile is a key driver, it is changing research and shopping habits, and in turn affecting supplier product cycles, merchandising and marketing strategies 

Social media has disrupted the traditional shopping funnel, changing how trends and styles proliferate and shifting the sites of authority and influence in a £66 billion sector

Amazon’s marketing services bring in a growing stream of direct, high-margin revenue, but their main role is still in supporting vendor partnerships

Amazon uses customer profile data to profit from its own media and that of others, illustrating the value of a direct customer relationship in online advertising

In the future, Amazon’s moves into video content and voice interfaces are likely to significantly expand ad inventory, but maintaining the trust of shoppers is not straightforward

Enterprise cloud computing democratises access to IT capacity ranging from specialised software to platforms to infrastructure, transforming cost structures in sectors like media and retail

Cloud enables unprecedented scalability of bandwidth for digital media services like Pokémon Go and Netflix, while also hosting the back-end for advertisers and retailers 

As the industry consolidates quickly, intense competition among Amazon, Microsoft and Google is delivering value to customers and boosting adoption

Netflix celebrated the 10-year anniversary of its streaming service by posting its largest quarterly rate of subscriber growth, adding just over 7m new subscribers in Q4 2016, smashing its own forecast for the period of 5.2m

5.12m of the new subscribers were for its international services, attributed to acceptance of its growing suite of English language original programs. But growth is just as likely related to the bolstering of overseas offerings with acquired programming, after launching worldwide with relatively small libraries

While re-establishing confidence after a period of doubt when missing targets in Q2, challenges await; most notably concerns around net neutrality, diversifying content genres, and the open question as to how effectively original programming will be able to carry the service

Streaming is now mainstream and we predict 113% growth in expenditure on subscriptions for 2015-18 in the top four markets (US, UK, Germany and France)

Free vs paid-for streaming is the central question for the music ecosystem: free yields fractions of pennies, making subscription the only credible business model

Market leader Spotify is facing competition from tech giants Amazon, Apple and Google, with deep pockets, for whom content is a pawn in a larger game

European mobile service revenue growth recovered to nearly reach positive growth in Q3, improving a whole percentage point over the previous quarter to -0.2%

The main driver of the improvement was continued ‘more for more’ price increases combined with a lack of price wars at the lower end, although the current detente does not feel very stable. Furthermore, the pressure on growth from the general trend towards SIM-only and the consequent lower contract revenue looks unlikely to alter

Revenue growth of around zero as almost achieved this quarter is sufficient for the operators to grow the bottom line, but not to transform their network coverage in the style envisaged by 5G enthusiasts – more substantial growth is needed to cover the costs of such a step-change

UK mobile service revenue growth improved in Q3 to -0.8% from -1.7% in the previous quarter, a welcome turnaround after three quarters of declining growth. Pricing remains firm, data volume growth remains robust, and some of the one-off factors affecting the previous quarter have dropped out

Sky Mobile soft-launched at the end of 2016, and it is taking an aggressive approach with a very deep MVNO technical model with substantial fixed costs, a high advertising budget and ambitious internal subscriber targets. To date the fixed MVNOs have not had a substantial impact on the MNOs, targeting a customer base that is non-core, but with SIM-only on the rise this may change

Looking at recently released network performance statistics, the impact of spectrum disparities is clear, with EE both able to offer faster speeds nationwide due to its large blocks of 4G spectrum, and offer much faster speeds in London. EE also has a lead in geographic coverage, and is planning to push its coverage much further, creating a challenge for the other operators to keep up

As smartphone ownership nears saturation in almost all consumer groups, the base for the UK digital economy is widening: media consumption continues to move to connected devices and use of consumer services on mobile grows

Ecommerce is now responsible for 75% of retail growth, steady even during periods of decline for the overall market

Google and Facebook take up almost 90% of gross online advertising growth this year, and the ecommerce and mobile service markets show early signs of platform concentration

US television advertising is rising in line with GDP, while the online video ad market is flourishing, with much appearing alongside the majors' scripted content

Studios' cable channels are their most profitable assets, but M&As with distribution platforms, including Comcast's aquisition of NBC Universal, have usually failed to deliver synergies

The Donald Trump presidency could leverage hostile public opinion towards mergers to undermine the AT&T bid for Time Warner; but it could also stimulate M&As if it granted tech companies a tax break to repatriate profits. A more protectionist administration could also bring about a less benevolent attitude towards majors' foreign operations
